Ford F-Series trucks are pretty popular in the United States, but they’re also top-sellers in Canada. But F-Series also makes an appearance on another list of popular vehicles in Canada; the most stolen vehicles list.

Several places, including the latest Insurance Institute for Highway Safety (IIHS) report, suggest that aluminum is more expensive to repair than steel, and will also mean insurance rates will be higher. Ford counters with their own numbers. The key here is Ford’s data comes from a much larger sample size, which matters.

We know the 2015 Ford F-150 has an aluminum body. We know the prices for its body parts are more or less what they were for the 2014 model year. We still don’t know what insurance rates for the trucks will ultimately be, though.
